Title: Control device for slidable panels actuated by electric motors
IPC: E05F15/16
Filed: 1971-12-30
Abstract: 1347739 Locks; window operating mechanism AUTOMOBILES PEUGEOT 30 Dec 1971 [11 Jan 1971] 60684/71 Headings E2A and E2M A device for controlling movable panels of a vehicle each panel being actuable by an electric motor, a lock mountable on at least one of the doors of the vehicle wherein relay means are provided for simultaneously actuating all of the motors for closing the panels and at least one switch controls the supply of power to the relay means and is mechanically connected to the lock or each lock and connected in series with the relay means. One or each front door of a vehicle has a key operated barrel lock the barrel of which is connected by a bar 3 to a locking member 5 which engages a lug 7 to lock a latch 7a. The bar 3 carries a bar 8 with a lateral projection 9 which when the door is locked closes a switch 10 and energises a relay 19 connected through the switch 18 to a battery. The switch 18 operates to close the circuit to drive the motor 11 of each panel. A thermal switch 17 in series with the motor 11 automatically cuts off the supply to the motor 11 when the panel has closed. The motor is in series with switches 15, 16 as shown in Fig. 6, the switch 16 being actuated to open the panels by the motors 11. The panels are closed independently of the door lock by actuating a switch 20 inside the vehicle. In order that all the doors be locked simultaneously whenone door is locked, the circuit includes a relay 21, both relays 19, 21 being connected to a switch 22, closure of which, ensures both locking of the doors and closure of the panels. A switch 23 connected between the coil 19 and two switches 10, when open, breaks the circuit for closure of the panels to enable the doors to be locked without competely closing the panels. The motor 11  has a worm 12 on a driven shaft, the worm being in mesh with a worm wheel 13 which carries an arm 14 on its axle the arm having a stirrup supporting the panel. The bar 3 engages in an aperture 4 in the locking member 5, the aperture having the shape of two opposed isosceles trapeziums whereby the barrel may return to its original position independently of the position of the locking member 5. The panels may be windows, sliding roof or hood of the vehicle.

Abstract: 754,390. Parachute harness. PIONEER PARACHUTE CO., Inc. April 6, 1954 [May 8, 1953], No. 10073/54. Class 141. [Also in Group XXV] A parachute harness, quickly releasable by the wearer without need for slipping out of the harness comprises a chest portion 36, Fig. 1, with side risers 8, 10 coupling the seat 2 and shoulder portions 16, 18 of the harness, separable couplings 12, 14 being provided in the side risers which completely release the chest portion from the shoulder portions. A separable coupling is provided in at least one side riser to release the chest portion from the seat portion, so that the chest portion will not remain connected to the harness at more than one point. The quickrelease mechanism comprises a drum 44, Fig. 4, connected by cables to the individual separable couplings and having a slotted arm which is cammed by the operator's handle 54 when this is moved along a slot 56 in the casing 38. For safety, a catch 62 guides the handle to the upper end of the slot 56, and only after complete upward movement of the handle is the catch released to allow the operator to make a separate movement of the handle along the slot 60 to swing the drum arm and thus tension the release cables of the separable couplings. One such cable, 66, is shown coupled to a bell-crank 94, an arm 90 of which actuates a latch 74 locking a lug 81 on the coupler 40, to the other coupling member 78. Specifications 339,388, [Class 44], 591,340, 611,794, 621,689 and 643,439 are referred to.

Title: Drill Pipe Wear Belt Assembly
IPC: E21B17/10
Filed: 1978-10-05
Abstract: A steel wear belt 27 having a prepared inner surface with an inner diameter large enough to pass over the weld upset on one end of a drill pipe tube 11 but too small to pass over the tool joints 17, 19 is installed about the pipe over a prepared outer peripheral surface thereof. Preferably the belt outer diameter is equal to or less than that of the tool joints. The belt is installed prior to one or both tool joints being welded to the tube. The belt is secured to the tube by a mounting layer 35 of high polymer material, e.g. plastics or elastomer, preferably self bonding and thermoset, between the prepared surfaces. The mounting layer may have a thickness in the range of 1/16 to 1/4 inch and an elastic modulus of not over 5% of that of steel, and an elastic shear strength of, e.g. 500 to 300 psi, and be stable up to 250 to 300 deg. F. The thickness of the mounting and its physical properties prevent stress concentration in the pipe due to mere attachment of the wear belt and due to restraint on pipe flexure imposed by the wear belt and prevent electrolytic corrosion between the pipe and wear belt. The pipe is plastic coated internally from tool joint to tool joint. The internal coating 25 and the wear belt mounting 35 are preferably cured simultaneously and may both be made of phenolic or epoxy, or preferably, phenolic-epoxy synthetic resin; otherwise an elastomer would be preferred for the belt mounting. <IMAGE>

Title: Device for controlling the travelling speed of a motor vehicle
IPC: B60K28/00
Filed: 1978-12-08
Abstract: A device for controlling the travelling speed of a motor vehicle has a differential amplifier 1 to which is fed a desired value signal and an actual value signal tapped from a potentiometer 13 across which a fixed reference voltage is applied. The differential amplifier 1 is coupled with a correcting motor 8 for adjusting the throttle valve 10. The device is connected so that when the throttle valve 10 is set for the maximum acceleration the slider 12 of the potentiometer 13 is at a low potential and when the throttle valve 10 is in the idling position the slider 12 is at a high potential. The slider 12 is connected via a fixed resistor 4 with that end of the potentiometer 13 which is opposite to that which is held at the higher voltage. Faults occurring in the feedback signalling circuit produce an actual valve signal which causes the throttle valve 10 to be closed and therefore dangerous situations are prevented. <IMAGE>

Patent GB-2041908-A (GB)
Title: Insulating Material
IPC: C04B32/00
Filed: 1980-01-29
Abstract: A foamed insulating material is produced from a soluble silicate binder such as sodium or potassium silicate, in which one or more finely divided fillers is incorporated. The fillers and the proportions in which they are used are selected so that, when thoroughly mixed with an aqueous solution of the silicate binder, each portion of the resulting foam insulator contains the ingredients for glass or ceramic formation which will take place if the insulating material is strongly heated, with consequent absorption of heat by the glass forming reaction. The fillers e.g. hydrated lime or hydrated alumina may also be provided in a form which undergoes endothermic reactions due to removal of water of crystallisation or to structural dissociation of the fillers. In order to reduce the solubility of the silicate, ion exchange is encouraged by the inclusion of calcium or magnesium salt in the fillers. Foam formation may be achieved by rapid, for example microwave, heating or by the use of air entraining agents. Low density or hollow fillers such as pfa cenospheres may also be included.
